I'm updating my stock shifter boot and handbrake boot with leather. I noticed that just above the a/c fan switch on the center console, there appears to be a microphone. If I turn it counter-clockwise and pull on it, out comes the (microphone?). On it, it has "run" and "stop". The wire that it attaches to is spring loaded so it winds itself back up whenever you let go. It looks factory so what is it? And please, no Mr. Microphone jokes!
